Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.
A partial lunar eclipse during moonrise will let viewers in most Australian capitals see the Moon partly shrouded in Earth’s shadow, while the “Moon illusion” makes it look larger than life.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
A new 3D film follows two children as they discover the astrophysical story of the universe and Yamaji stories of the sky and land. Making it was an extraordinary cross-cultural experience.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
Preprints are scientific papers made available before being published in a peer-reviewed journal. The Australian Research Council has banned researchers from citing them in grant applications.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
